[What is adult ADHD after all?]

Attention-deficit/hyperactivity disorder (ADHD) is a childhood-onset mental disorder, demonstrates genetical effects, and is characterized by attention deficit, hyperactivity, and impulsivity. While ADHD was previously only considered a childhood disorder, longitudinal studies over the past decades have proven that in a significant number of cases, the symptoms of the disorder can also be detected in adulthood, and therefore affects 2-4% of the adult population. In Hungary, adult ADHD programs started about 20 years ago and has been able to provide help to many adults living with ADHD. However, this form of care needs further development in many aspects and suffers from capacity deficits at the national level. On July 4-6, 2023 we organized a CME course on adult ADHD at the Department of Psychiatry and Psychotherapy Semmelweis University. The objective of this course was to deepen the knowledge of participants and alleviate care difficulties in the long term through the sharing of information and good practices. As part of this, a narrative review was written, which touches on the current issues of diagnosing and treating ADHD in adults.
